supporting. frame is preferably secured to the side sills of the vehicle frame 10 by means of bolts 21.

Surrounding the jack shaft 17 and preferably located intermediate the ends thereof is a sleeve 22 the through-opening or bore of which is provided with key ways 23, which receive thelongitudinally disposed keys 24 secured to the shaft 17 as clearly shown in Fig. 6. By this arrangement the jack shaft iscaused to rotate'when the sleeve is driven and at the same time the longitudinal or sliding movement of the sleeve relative to the jack shaft isprovided for.

provided with gear receiving portions 25 which are of reduced diametenand over these portions oppositely disposed bevel gears 26 are adapted to be slipped. Ex-

tending outwardlyfrom the ends of the centheir internal peripheries threads of the same pitch as the threads 29 so that the rings may be screwed upon the threaded portions of the sleeve and against the bevel gears to retain the latter in place; The rings30 have V recesses31 for the-reception of a spanner wrench or other suitable tool.

At each end of the sleeve 22 is a cylindrical'portion 32 having a shoulder 33 atits innerend. Adapted to fit about the outer end of each of the cylindrical portions 32 of the sleeve is'an annular ring 34 secured in place-by means of'a sct screw 35. Betweenthe ring-34 and shoulder 33 is a groove which receives a strap 36, this strap being in the form of a ring composed of two'parts' secured together by bolts 37. The sleeve rotates within the straps36. It is to be noted that by making the straps 36 in two parts they may be readily inserted in'place. and that thering's 34 may bereadily' adjusted lengthwise of the sleeve so as to take up any loose motion due to wear of the parts. Each of the straps 36 is provided with a pairjof diametrically disposed radially extending stu'dsor'gudgeons' 38. 1 I

The meansfforshifting the sleeve 22 together witliythe gears carried thereby comprisesyin part,shipper levers-39. As shown in Fig. 6, these levers are each composed of tWGStilDSiOf metal bent outwardly intermediate their ends soas to provide'loops The sleeve adjacent its opposite end is which receive the straps '36. The shipper levers have slots 40 which receive the studs 38 of the straps 36. The shipper levers are in parallelism with each other and are piv0ted at their rear ends tothe transverse member 20 of the supporting frame. The forward or free ends of the shipper levers 39are connected together by means of a cross-rod 41-and, preferably, the opposed faces of the forward ends of the strips of the shipper levers are rabbeted' so as to provide recesses which receive the ends'of the rod41as is clearly shown'in Fig.6. It "will be seen from Fig. 3 that the-forward ends of" the shipper levers restand slide upon the forward transverse membe'r 20 of thesupporting frame.

The cross-rod 41 is connected by means of a pin-and-slot connection 42 to the" arm of the bell crank-lever 43. The lever 43 is in the form of a T and is pivoted, wherefits arms intersect to a supporting-bar 44 car ried by the supporting frame and extending beneath the drive shaftf15. One of the ends of the transversemember of the T lever 43 is connected by means of a rod 45 to a lever 46 pivoted intermediate its ends to a standard 47, (see FigplO). An operating handle 48 is provided with a longitudinal bore at its lower end into which the upper end of the lever 46 projects, and within the bore and engaging at one end against the upper end of the lever-'46 is a spring 49 for normally ur ing "the handle 48; The handle 48carries a V detent orfinger which is adapted to engage in the notches 50 ofthe segmental portion of the standardfor'the purpose of locking the reversing'gears' in adjusted position. In

the present instance three such notches are illustrated so that the reversing gears 26 maybe locked in forward, central and reversed positionsrespectively. It is understood,'of course, that the hand operating mechanism illustrated in Fig. 10, is shown byway of illustrationonly, and that any i suitable lever mechanism may be employed. 5

The rod 45 is connected to theleftor right hand end ofthe T lever 43, depending "on the position of For the purpose of locking the reversing gears 26 in adjusted position and maintaining'either of them in mesh with the' drive notch 52 for the reception of the forward endso'f the shipper levers 39. p The dogs are pivota'lly connected to the opposlte ends of a plate 53 secured centrally of the forward member 20 of the supporting frame and, preferably, the plate 50 also carriesa bearthe operating mechanism of the' vehlcle.

- gear 16; l-provide a pair ofoppositely dis posed dogs or latches 5i, each having a ing blcck 54 for the drive shaft 15 ofthe engine. a a V The dogs or latches 51 are so disposed relative to the shipper levers that-whenthe reversing gears are in neutral position, that is, when'neither of'tlresegears isininesh with the'dri've gear 16of the engineythe shipper levers I 39 lie outside of the notches -52- of the dogs. Asthere are'no'side thrusts on the reversing'gearswhen in this position,

the handle 48 is sufficieat to retain them in adjusted position;

When it is desired' tddrive the vehicle in a forward direction one of the reversing gears, in the resentfin'stance the right hand one, referring to Fig; l. is thrownlnto mesh with the drive gear 16 by ino ingthe handle 4S forwardly and *thiis *rocklng' the T-lever" 43'so as to swingthefofrward ends otth'e" shipper levers to the left and move the right-hand shipper lever into position where it will engage in the notch'52 of tlier1ght hand dogtl; VVhenf the drive gear'lsis in mesh with one of the reversing gears 26 there" 1s a tendency to force the reversing gear away fr0nrthe drive gear, but byengagenient ofthe shipper lever39 within the notch 52, movement ofthesleeve', together with the reversing gears carried thereby is guarded against. Theshipperlever's and the 7 dog are inadesufiiciently strong to"resist any strainenerted upon them; lVhen' it is freeends of the dogs51; I have disclosed the dogs as being connected by nieans'ot chains 55 tothe opp'osite endsbfa pivoted bar56. The bar 56 is conneeted'byrneans of a rod 57, to a suitable hand operating mechanism, which i may be sirnil ar" in strutture to the mechanism illustrated i'nFig. 10'. By rocking the barte in theproper "direc tion, the dog which is 1 securing one of the shipper levers 39 inav be lifted to permit shifting of the reversing gears. Preferably;

each of thedogs 51'has a lower inclined surface 58 soth'at it is not necessary to" raise both of the dogs simultaneously; asthe ship per levers 39 when moving toward the pivotal points of-the dogs automatically raise the latter;

In'the einbodiment'of my invention disv closed in 'Figs. 4, 5 and 7; I ha ve'illustrateth for the purposeof showing one of tlie'nunierou's applications of my invention of whichit is susceptible; my improvedreversing mechanism as appliedto a caraxle of the type to which the car wheelsare fixed. 59 designates the axle head and 60 the-oar wheels fixedto theaxleu The trade 59is of reduced diameter intermediateits ends an d about the re'ducedxportion of the axle, the sleeve 22 is rnounted. Initlns embodiment of-my invention; l the sleeve-22 isaconstrncted of two=com lementaryparts; and each of the partshas a"key'-way 23 forthe reception ofheysfl' l carried by'the 'axlei One part of thesleeve22" has its internal longitudinal edgesrabbeted' as at 61st) as to'provide longitudinal ribs 62 along its outer periph eral' ed ges and the"othei 'ineinber is rabbeted adjacent itsouter edges as *at 68'so to provide loiigitu'dinal ribs 64 adjacentits inner eripheral edges; The ribs 62 'enga'ge in the rabb'eted recesses 63, and the ribs 64in the rabbeted I'BCQSSQSGlySO 'bhiLt theparts are interlocked and cannot" become laterally displaced after they are properly cured together. Thesleeve 22" hasanenlarged central portion, gear-receiving i portions '25, threaded portions 29', and cylin-' drical extensions 32. Reversing gea'rs 26 are retained in place upon the gear=receiving portions 25 by i'ethiiiiiigriiigs threaded on the threaded portion 29", as in the preceding embodiment. In this instance the outer ends" of the cylindrical portions32 are ofredilced diameter a-nd are threaded at The two partsof the sleeve 25 are secured together by-lneans of rings "66 clearly shown in Figs. 4L and 5. Thesering'sare made of tWo complementary partsand are secured togetherby means o'fbolts 67, the rings being recessed as at 68 so as to receive the heads ofthebolt's. Therings 66 are o'fsuch thickness that their outer peripheries are flush with the peripheries of the portions 32 of the sleeve 22 so thatthe straps 36 and the rings 34 may be slippedover the ends of the sleeve after it has been assembledon the ELXlQ 59. i

It will be noted that by splittingthe sleeve 22 longitudinally into twosemi-cylindrical parts; the sleevema'y be readilyapplied to and removed from the car aXle'. If desired, each of thegears26 may be made in two parts suitably bolted together. The split rings" 66 primarily hold the parts of the sleeve together, and thegeai's26, rings 34, and straps 36, reinforce the sleeve.

The sleeve 22 disclosed in Figs-4, 5 and'i', maybe employedin the embodiment of my invention disclosed in Figs. 1 and 2, and my invention is susceptible to various inedifications and changes which will be within the scope of the invention without departing from the spirit of the same.
